  • What happened to 3D printing, why did it disappear in just two years?

Almost every month, I can see a lot of papers about 3D printing. On the subject of 3D printing, the school is completing 3D printing projects related to industry, they print the aviation and automobile engines and start to apply to the industry, they also print gold. Silver jewelry, serving students of the School of Art. Perhaps the engine of the aircraft we are flying is already 3D printed or has been used in 3D printing on the communication satellite.
